I COUPLING FORBATTERY ELEMENTS.

Specification of Letters Patent;

Iatented Jan. 1, 1907.

Application filed January 22, 1906. Serial No.'297,140.

Be it known that I, FRANK A. Dncxna, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia. and State of Pennsylvania, have invented certain Improvements in'Couplings for Battery Elements, of which the following is a specification. V,

This invention is an improved coupling for battery elements, providing means whereby such elements can'be readilyoonnected and disconnected both electrically and mechanically, with relation to the cell in which they are-used.

In its preferred form it comprises, generpered car secured to the element to be me- In the accompanying drawin s, Figure 1 represents a perspective view the invention. 2 ma plan'view representing a developed form oftlie construction shown in Fig. 1'. Fi'L-3 J'sa .perspective view of the terminal ho der shown in F 2. Fig. 4 is a perspective view of a mod' 'ed form of the construction shown in Fig. 2, and Fig. 5 is a perspective view of a modified form of the construction shown-in Fig. 1.

"In the form of the invention shown in Fig. 1 the plate '1 has fixed thereon the ear Quin the form of a ta cred plug, and the holder 3 of suitable con ucting material has'therein the tapered socket 4, which receives the ear, and the slot 5, which receives the plate, the

art 3 having abinding-scrcw 6 set therein or securing it to the envelop and the conducin the socket and in its final position makes a close connection therewith. I 1 In Figs. Z'and 3 isshowna compound form" of the holder comprising the parts 7, contain; ing the socketsfl and the slots 9-, which are connected by the part 10, having the threaded hole 11 tapped therein. A binding-screw 12, passing through the conductor 13 and the.

gagement in the hole 11. The ta cred plugs 15 are engaged in the comes on ing sockets 8 and support the plates 16, xed thereto and 'held thereb in the cups 17, having on either side thereo and supported thereby the electrodes 18. r

In Fig. 4 is shown a compound holder in l e part 19, connecting the parts 20, 1

has thereon the lug 21, while the element 22 is provided witha tapered car 23, bent up from sheet metal, with the straps 24 thereon riveted to the plate, each socket 25 of the holder receiving an car 23, which enters, as shown, and drops down to a tight connection.

In the foregoing'preferred constructions the plug and the socket taper downwardly in the direction of their extension, being joined and separated by moving them vertically in the direction of their axes and parallel to the direction of movement of the plate in inserting and withdrawin it, the weight of the plate acting to force t 1cm together along the line of their axes..

In F i 5 is shown a construction in which the holder 26 has the horizontall disposed socket 27 therein tapering from t e back to the front and opening through the vertical slot 2S,'and the plate 29 has the horizontallydisposed car 30, turned up to tapered form from the metal thereof, on which the holder is adapted to be slipped,a threaded hole 31 in the holder providing means for engaging it in position by means of a binding-screw.

Having described my invention, I clain1 1. A coupling for battery parts comprising, in combination with a plate, a device afixed to said plate and a second device for engaging and holding said first device, saiddevices being forced one within the other and held in close relation by the weight of the plate. 1

2. Aj'conpling comprising a tapered socket and a tapered plug, in combination-with a plate secured to onset said parts, and an envelop and-conductor secured to the other of said parts,the axes of said socket and plu being disposed vertically in their assemble relation.

3. A battery-electrode holder having a tepered socket and a slit therein, an envelop and a conductor to which said holder is engaged, and an electrode having an ear thereon which fits said socket and has its connec-, tion with said electrode dis osed in said slot,

In testimony whereof I ave hereunto set my hand, this 19th day of January, 1906, in the presence of the subscribing witnesses.
